ProFTPd服务器的安装和配置

下载最新版本

1.将刚刚下载的proftpd解压缩：

[root@tet root]# wget \

>  http://ftp.nsysu.edu.tw/Unix/FTP/proftpd/distrib/source/proftpd-1.3.3.tar. gz

[root@test root]# cd /usr/local/src

[root@test src]# tar -zxvf /root/proftpd-1.3.3.tar.gz

# ...(略)...会主动产生proftpd-1.3.3的目录

[root@test src]# cd proftpd-1.3.3

#在这个目录底下的 INSTALL 请详细的阅读，里面有安装的几个重要资讯！

2.进行编译前的参数设定：

[root@test proftpd-1.3.3]# ./configure --prefix=/usr/local/proftpd \

> --enable-shadow --enable-autoshadow \

> --with -modules=mod_ratio:mod_readme:mod_wrap

#请注意，那个prefix表示我预计要安装proftpd的目录；

#至于--enable-shadow与--enable-autoshadow则是预计要以

#系统的/etc/shadow做为我的FTP登入时的密码验证档案！

#此外，还加入许多的支援模组，会让我们的Proftpd变的更活泼！

[root@test proftpd-1.3.3]# make && make install

#经过这个步骤之后，你的proftpd就会安装在/usr/local/proftpd之内，

#其中，设定档在/usr/local/proftpd/ etc/proftpd.conf ！

#至于说明档(man pages)则在/usr/local/proftpd/man当中！

3.设定一些查询的相关功能！

[root@test proftpd-1.3.3]# vi /etc/man.config

#加入底下这一行，这样才能以man来查询指令的用法！

MANPATH /usr/local/proftpd/man

4.设置xinetd 来启动proftpd

事实上，目前大部分的FTP daemon 多是以super daemon 来启动的！所以这里我们也直接以xinetd 来设定proftpd 吧！毕竟多了一层管理，会更安全的啊！^_^！设定的方法也真是很简单～只要编辑xinetd 底下的proftpd 以及proftpd.conf 档案里面的一些内容即可！

[root@test root]# vi /etc/xinetd.d/proftpd

service ftp

{

  disable         = no

       flags = REUSE

       socket_type = stream

       wait = no

       user = root

  server          = /usr/local/proftpd/sbin/proftpd

       server_args = -c /usr/local/proftpd/etc/proftpd.conf 

       log_on_success += DURATION USERID

       log_on_failure += USERID

}

#上面的重点在于两行粗体字的地方！尤其是server =..那一行！

#由于我们是使用Tarball安装的，自然就以我们的档案放置目录为主，

#如果您使用RPM安装，这里就不太相同??

#另外，那个server_args后面接的则是设定档的档名咯！

[root@test root]# vi /usr/local/proftpd/etc/proftpd.conf

#找到底下这个设定值：

ServerType standalone

Group nogroup

#因为我们的系统预设并没有nogroup这个群组，所以必须要将他改成

#系统里面有的群组才行呐！而伺服器启动的方式有super daemon与 

# stand alone ，所以：

ServerType inetd

Group nobody

[root@test root]# /etc/rc.d/init.d/xinetd restart

[root@test root]# netstat -tlnp

tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 8483/xinetd

#呵呵！21这个埠口出现了！理论上没有问题，不过还是需要分析一下

# /var/log/messages这个档案的内容才行喔！

proftpd配置:

# This is a basic ProFTPD configuration file (rename it to

# 'proftpd.conf' for actual use.  It establishes a single server

# and a single anonymous login.  It assumes that you have a user/group

# "nobody" and "ftp" for normal operation and anon.

ServerName                      "ProFTPD Default Installation"

#其中password1可以用apache2自带的htpasswd -n username1 自动生成

# Port 21 is the standard FTP port.

# Umask 022 is a good standard umask to prevent new dirs and files

# from being group and world writable.

Umask                           022

# To prevent DoS attacks, set the maximum number of child processes

# to 30.  If you need to allow more than 30 concurrent connections

# at once, simply increase this value.  Note that this ONLY works

# in standalone mode, in inetd mode you should use an inetd server

# that allows you to limit maximum number of processes per service

# (such as xinetd).

MaxInstances                    30

# Set the user and group under which the server will run.

User                            nobody

Group                           nobody

# To cause every FTP user to be "jailed" (chrooted) into their home
